Corticosteroids for Nerve Regeneration: A Narrative Review

Area of Science:

• Neuroscience
• Regenerative Medicine
• Pharmacology

Background:

• Peripheral nerve injuries affect roughly one-third of patients, leading to inadequate functional recovery despite advanced microsurgery.
• Nerve damage causes significant pathophysiological changes, including morphological and metabolic alterations.
• Current pharmaceutical options for enhancing nerve regeneration are limited, necessitating further investigation.

Purpose of the Study:

• To explore the mechanism of action of specific corticosteroids in peripheral nerve regeneration.
• To highlight the potential of corticosteroids in improving outcomes following nerve injury.

Main Methods:

• Review of animal research studies investigating nerve regeneration.
• Analysis of the effects of corticosteroids (Dexamethasone, Betamethasone, Methylprednisolone) on nerve healing.
• Examination of functional and histological parameters post-nerve injury.

Main Results:

• Animal studies suggest certain medications can accelerate nerve regeneration.
• Factors influencing regeneration include injury type, age, time, procedures, and materials.
• Complete functional recovery remains challenging even with pharmaceutical interventions.

Conclusions:

• Corticosteroids demonstrate potential in enhancing peripheral nerve regeneration.
• Optimizing corticosteroid dosage and combination therapy may improve clinical outcomes.
• Further research is crucial to fully harness the regenerative potential of these agents for nerve injury.
